I'm curious if anybody has any negatives about using spacers to lift the runner. I have a stock 2003 V6 SR5 4Runner and really looking into installing 2.5inch spacers and adding beefier tires. Does anyone know how high the truck will actually be raised?? I heard some negatives of spacers are that they sag over time. Oh yeah btw, the kit i bought are Daystar's. Any input or info would be great! Thanks.
